Madison Reed hair color comes in a bottle with a helpful nozzle tip designed to easily separate your hair into smaller sections in the areas that you cannot see as you color. Use the nozzle to create small 1/4th" rows, one section at a time. Use plenty of product to make sure you are fully saturating your roots for full coverage. You should use about half the bottle on your roots. Once you have finished applying, go back and massage the color into your roots one last time before moving onto the next step in the instructions.
